Justification:
Listed as Vulnerable because its Extent of Occurrence is less than 20,000 km2, its distribution is severely fragmented, and there is continuing decline in the extent and quality of its forest habitat on Luzon and Sibuyan in the Philippines.

This species is found in the mountains of the Central Cordilleras and Sierra Madres, on northern Luzon Island, and on Sibuyan Island, in the Philippines. It ranges from 400-1,000m asl (R. Brown pers. comm.).

Its range includes a few protected areas, but there remains a need for improved protection of remaining forests in the Central Cordilleras and Sierra Madres on Luzon. As its species name suggests, this is one of the smallest frogs in the Philippines (as small as 15mm in snout-vent length), and so could represent an important flagship species for conservation efforts in the region. There is also a need for further taxonomic research to resolve what might be a species complex.
